an AT-AT battle on a white planet
No, it is the premise of the OT in simply the vaguest of definitions.
So you’re nitpicking visual similarities now? But then, the planet isn’t really white, it’s red, with a white cover and when the salt is blown away, the visual similarities start to vanish.
It’s not really white? It just looks that way? I see, it’s Mars disguised as Hoth. Seriously though, we have a white planet, and a walker assault on a rebel base. Sounds like a Hoth reprise to me. It’s Hoth with a twist, like almost everything in the ST is the OT with a twist. Adding a twist does not make a story thread original. This to me is the ST’s greatest weakness. It should have told an original story, that flows naturally from the OT. In stead it largely rehashes the OT, adds a few twists, and deconstructs the classical characters to fit the mold.
